(Embodiment of the Invention)

Hereinafter, the present invention will be described in detail.

The shape change fiber bag of this invention has a water swelling layer which has arrange | positioned the water-insoluble water swellable resin in a pattern form as outermost layer on one side or both sides of a fiber bag.

In the present invention, the material of the fiber cloth is synthetic fibers such as polyester, nylon, acrylic, polyvinyl alcohol, regenerated fibers such as rayon, natural fibers such as cotton, hemp, wool, silk, blends thereof, and knitted fabrics (交 編織 品), is not particularly limited. Moreover, as such a form, anything, such as a woven fabric, a knitted fabric, and a nonwoven fabric, may be sufficient.

Moreover, it is preferable that the water swelling degree of the water-insoluble water swellable resin used for this invention is 5 to 100%, especially 10 to 50%. If the water swelling degree is less than 5%, there is a fear that the shape change of the fiber cloth is small and the sticky feeling may not be eliminated. If the content is larger than 100%, the three-dimensional change of the fiber cloth becomes too large, the resin may easily fall off from the fiber cloth upon absorption, or the fit may be impaired.

Here, the water swelling rate means the volume increase rate when the absorption becomes substantially saturated at room temperature (20 ° C.), and is usually expressed by the volume increase rate after immersing the dried resin piece in distilled water at 20 ° C. for 24 hours. .

The water-insoluble water swellable resin used in the present invention is a resin which is substantially water-insoluble under the use environment and absorbs and swells in the presence of moisture or water, and is starch-acrylate resin, polyacrylate-based resin, and polyvinyl alcohol-based resin. Resin, vinyl acetate-acrylate resin, isobutylene-maleic acid resin, poly-N-vinylacetamide resin, polyether urethane resin, polyester urethane resin, polyester polyether urethane resin, poly Carbonate-type urethane resin etc. can be used. In particular, a polyether urethane resin is preferably used in view of resin adhesiveness, abrasion durability, and moisture permeability. Specifically, as a polyether urethane resin, Sanprene HMP-17A (manufactured by Sanyo Chemical Co., Ltd.) and Heimene Y301-3 (made by Daiichi Seika Industries Co., Ltd.) and Crisbon S525 (made by Japan Nippon Ink Chemical Co., Ltd.) etc. are mentioned.

Moreover, in order to improve adhesiveness, it is preferable to add crosslinking agents, such as an isocyanate type, a carbodiimide type, and an epoxy type, to water-insoluble water swellable resin. In addition, fine powders of inorganic or organic substances such as pigments, dyes, surfactants, plasticizers, calcium carbonate, titanium oxide, colloidal silicic acid, cellulose, and protein can be added within a range that does not impair water swellability and fit.

In the present invention, the water-insoluble water swellable resin is imparted to the outermost layer in a pattern (i.e. partly over the entire surface area) directly or through the other layer on one or both sides of the fabric fabric. As the pattern, a uniform pattern, in particular, an island-in-water pattern (the water-insoluble water-swellable resin may form an island of a discontinuous layer or may form a sea of a continuous layer) and a parallel pattern is preferable. Examples of island (dot) shapes of the island-in-the-sea pattern include polygons such as triangles and squares, circles, and ellipses. As a linear form of a parallel line pattern (stripe pattern), a straight line, a curve, a cutting line etc. are mentioned. Although the pattern space | interval (dot space | interval and the thickness thickness of a parallel line) can be suitably determined, it is 1-30 mm, especially 3-15 mm is preferable normally.

As for the thickness of the resin part which becomes water-insoluble water swellable resin, 1-300 micrometers, especially 5-15 micrometers are preferable. If it is smaller than 1 µm, the change in shape of the fiber cloth is small, and there is a fear that the sticky feeling will not be eliminated. If it is larger than 300 µm, there may be a feeling of discomfort when worn, or the resin may easily fall off from the fiber cloth during absorption and swelling. have.

The area ratio of the water-insoluble water-swellable resin part to the surface area of the fiber cloth is preferably 5 to 90%, particularly 10 to 60%. If it is less than 5%, the change in shape of the fiber cloth is small, and there is a fear that the feeling of stickiness may not be eliminated. If it is greater than 90%, there is a fear of discomfort when worn.

As a method of apply | coating to the fiber cloth of water-insoluble water swellable resin, transfer, gravure coating, screen printing, rotary printing, etc. are mentioned, It is preferable to apply with gravure coating, screen printing, or rotary printing.

By using the gravure coating method, the screen printing method or the rotary printing method, the shape and thickness of the resin portion can be easily adjusted. That is, in the gravure coating method, the screen printing method, or the rotary printing method, by providing a predetermined shape on the gravure roll screen printing plate or the rotary printing plate to be used, it is possible to easily form a resin part having a predetermined pattern on the fiber cloth. Done. Moreover, since it can apply | coat continuously, mass production also becomes possible and it is excellent in productivity.

In the second aspect of the present invention, the water-insoluble water swellable resin is provided in a pattern form after the waterproof continuous layer is provided on one or both surfaces of the fabric fabric. This causes a change in shape due to the difference in the water swelling ratio between the waterproof layer and the water swelling layer, and therefore, the resin constituting the waterproof layer needs to have no water swellability.

As a resin which does not have water swellability which forms the waterproof layer which can be used by this invention, polyester urethane resin, polyether urethane resin, polycarbonate urethane resin, acrylic resin, synthetic rubber, polyvinyl chloride resin etc. can be used. Can be. In particular, a microporous membrane containing urethane resin as a main component and a nonporous membrane containing urethane resin having moisture permeability as a main component are preferably used. Specifically, as resin for a microporous membrane, the resin CU4555HV (made by Dainichi Seika Co., Ltd.) and Krisbon MP859 (made by Nippon Ink Chemical Co., Ltd.) of polyester-type urethane resin are mentioned, for example. Examples of the resin for the non-porous film include Krisbon NYT-18 (manufactured by Japan Nippon Ink Chemical Co., Ltd.), Heimene NPU5 (manufactured by Daiichi Seika Industry Co., Ltd.), and the like of a polyether urethane resin.

The resin used for the waterproofing layer is a resin which is substantially free of water swellability (even 5% or less), and the waterproofing layer generally refers to waterproofing of 1000 mm or more by the low water pressure method of JIS L 1092. In particular, a moisture-permeable waterproof layer is preferable. In particular, it is preferable to show the moisture permeability of 3000 g / m <2> * 24hr or more by the calcium chloride method (A-1 method) of JISL101.

Although the provision of the water-swelling layer of the pattern which consists of a water-insoluble water-swellable resin on a water-resistant continuous layer can be performed as mentioned above, when providing a water-proof layer, water swelling ratio is 5-50%, Furthermore, 10-30% Is particularly preferred.

If the water swelling ratio is less than 5%, the shape change of the fiber cloth is small, and there is a fear that the feeling of stickiness is not solved without reducing the contact area to the skin. Moreover, when larger than 50%, there exists a possibility that adhesiveness with a waterproof layer may fall, and it will fall easily.

Moreover, it is preferable that it is 10 to 80%, and, as for the area ratio of the water swelling layer with respect to a waterproof layer, it is more preferable that it is 20 to 60%. If the covering area is less than 10%, the stress difference due to the swelling difference between the two layers is less likely to occur, the change in form does not occur, or the convex portion caused by the change in shape is less, and the fabric cloth is in contact with the skin to reduce the feeling of sticking. There is a possibility that you can not. In addition, if the covering area exceeds 80%, there are too many convex portions, so that the contact area to the skin cannot be reduced, the feeling of stickiness cannot be reduced, and there is a fear that the texture becomes hard.

Fig. 1 is a schematic plan view showing a typical example of the outermost layer of the morphological change fabric bag of the present invention, where 1 is a water-insoluble water swellable resin part, and the lower layer is a fiber bag 2 or a waterproof layer 3.

Fig. 2 is a schematic cross-sectional view showing the dry state (A and C) and the water-swelled state (B and D) of the morphologically changed fabric fabric of the present invention. As shown in FIG. 2A (without a waterproof layer) and FIG. 2C (with a waterproof layer 2), the water-swellable resin 1 is partially arranged in a pattern, which absorbs sweat and condensation generated during exercise or the like. Swelling. However, a stress difference occurs in the lower fabric layer and the waterproof layer, and the stress difference causes the lower layer and the fabric layer to be pushed out, and as shown in FIG. 2B (without a waterproof layer) or FIG. 2D (with a waterproof layer) Change fabric changes shape. Moreover, the water swellable resin shrinks at the time of drying, and the stress difference with a lower layer disappears by that, and a form also returns to the original as a whole.

(Industrial use)

According to the present invention, when the garment which is the morphological fiber cloth of the present invention is worn, even if sweating at the time of wearing, the fabric bag absorbs moisture due to sweating, and the shape of the fiber cloth absorbing moisture is changed in three dimensions. Therefore, since the contact area between the fiber cloth containing water and the surface of the skin is reduced, the feeling of stickiness caused by the fiber cloth sticking to the skin surface is reduced, and the wearing comfort is remarkably improved. In addition, when dried, it reversibly returns to its original planar shape, thereby providing a comfortable fit to the wearer.

In addition, since the change in shape reversibly occurs without significantly impairing the mechanical properties and dyeing fastnesses of the fiber fabric, the comfortableness is excellent and can be sufficiently tolerated for practical use. . Moreover, the manufacture is easy and does not limit the fiber to be used, and is excellent in versatility.

For this reason, the shape change fiber cloth of this invention can be used effectively for innerwear, sportswear, raincoat, etc.
